Normally, the table component automatically starts and stops the editing of table cells based on user input. However, when building table commands, it may be necessary to programmatically enable and disable editing of cells. The following code demonstrates how to set a cell in edit mode: 
    // Create table
    int rows = 10;
    int cols = 5;
    JTable table = new JTable(rows, cols);
    
    // Enable the ability to select a single cell
    table.setColumnSelectionAllowed(true);
    table.setRowSelectionAllowed(true);
    
    // Set the cell on the 2nd row, 4th column in edit mode
    int row = 1;
    int col = 3;
    boolean success = table.editCellAt(row, col);
    if (success) {
        // Select cell
        boolean toggle = false;
        boolean extend = false;
        table.changeSelection(row, col, toggle, extend);
    } else {
        // Cell could not be edited
    }

The following code saves the current value in the cell being edited and stops the editing process: 
    if (table.getCellEditor() != null) {
        table.getCellEditor().stopCellEditing();
    }

The following code discards any changes made by the user and stops the editing process: 
    if (table.getCellEditor() != null) {
        table.getCellEditor().cancelCellEditing();
    }
